Using DUB version v0.9.19.

I've tried using this package: 

{
	"description": "dchip",
	"targetName": "dchip",
	"authors": [
		"Andrej Mitrovic"
	],
	"version": "~master",
	"homepage": "https://github.com/AndrejMitrovic/dchip",
	"name": "dchip",
	"copyright": "Copyright © 2013, Andrej Mitrovic",
	"targetType": "staticLibrary",
	"sourcePaths": [
		"src"
	],
	"configurations": [
		{
			"name": "demo",
			"targetType": "executable",
			"targetName": "example-app",
			"sourcePaths": [
				"tests/demo",
				"tests/lib"
			],
            "importPaths": [
				"tests/lib"
			],
            "versions": [
				"CHIP_ALLOW_PRIVATE_ACCESS"
			],
            "libs": [
                "tests/lib/glfw3_implib"
            ],
            "targetPath" : "demo_app"
		},
	]
}

And then I've tried running with: 

C:\dev\projects\dchip>dub --config=demo
Checking dependencies in 'C:\dev\projects\dchip'
Building configuration "demo", build type debug
Compiling...
DMD v2.064 DEBUG
Linking...
DMD v2.064 DEBUG
Error: C:\dev\projects\dchip\demo_app: The system cannot find the file specified.

Then I've tried using an absolute path: 

"targetPath" : "C:\demo_app"

Called it again: 

C:\dev\projects\dchip>dub --config=demo
Checking dependencies in 'C:\dev\projects\dchip'
Building configuration "demo", build type debug
Compiling...
DMD v2.064 DEBUG
Linking...
DMD v2.064 DEBUG
Error: Trying to append absolute path.

And then I just tried using the defaults, so I removed targetPath and built: 

C:\dev\projects\dchip>dub --config=demo
Checking dependencies in 'C:\dev\projects\dchip'
Building configuration "demo", build type debug
Compiling...
DMD v2.064 DEBUG
Linking...
DMD v2.064 DEBUG
Running C:\Users\ADMINI~1\AppData\Local\Temp\dub\2055224000\example-app.exe...
Error: Program exited with code -1073741515

Run 'dub help' for usage information.

So I want to inspect what went wrong with the executable, but then I see dub has actually deleted it. Why would it remove the generated exe if it failed to run properly? I can't inspect it if it's gone.
